Is there any way to merge multiple op's between any two versions?

[Xheldon]

For intance, a docs have three version, A ,B, C
A contents is : github
B content is: gb
C content is: gitbit
thus there has two ops:

A ---delete text(delete 'ithb')---> B ---insert text(add 'it' after 'g' and add 'it' after 'b')---> C

So, is there any way to get the merged ops between version a to version c? The merged op above should be:

A ---delete text (delete 'hu') & insert text (add 'it' after 'b') ---> C

Any help are welcome!

You'll want to use backend.getOps() to get the appropriate ops.

Then you can use your type's compose() method to merge the ops together.
